Hint: Soil erosion is commonly characterized as the loosening or washing away of soil particles in the oceans, rivers, valleys, streams, or faraway areas. Erosion occurs and worsens as a result of human activities such as deforestation and agriculture. Erosion is a continuous process that can happen at a slow or rapid pace. It causes topsoil erosion, ecological degradation, soil collapse, and other problems.
Soil erosion is defined as the displacement of the upper layer of the soil as a result of any environmental influence. This impact can be triggered by both biotic and abiotic factors.
The following are some of the major causes of soil erosion:
Rainfall and Flooding: Soil erosion is primarily caused by heavy rainstorms. The soil is washed away by the showers and washed into surrounding streams and rivers. Soil loss is disproportionately high in areas where rainfall is severe and frequent. During floods, the running water erodes a lot of soil, causing potholes, rock-cut basins, and other problems.
Agriculture: Deforestation for Agriculture Is One of the Top Causes of Soil Erosion. The increasingly high demand of a growing population for commodities such as coffee, soybean, palm oil or wheat is clearing land for agriculture.
Grazing: The grazing animals prey on the grasses and deplete the land's vegetation. The dirt despises their hooves. Plants are also pulled out by their roots. This causes the soil to relax, making it more prone to erosion.
Mining and logging: The logging procedure is impeded by the presence of a high number of trees. Trees securely hold the soil in place. Because of the shade provided by the trees, the soil is protected from eroding due to excessive rainfall. During logging, the leaf litter that protects the soil from erosion is nearly completely destroyed. Mining also disturbs the terrain, making the soil more susceptible to erosion.
Construction: The erosion of soil occurs as a result of the development of roads and structures. For construction purposes, forests and meadows are destroyed, exposing the soil and making it vulnerable to erosion.
Rivers and Streams: The V-shaped erosion activity is reduced when soil particles are carried away by flowing rivers and streams.
Strong Winds: The minute soil particles are carried away by the wind to faraway countries during dry weather or in semi-arid zones. Desertification occurs as a result of this degradation of the soil.
Note: Note that land deterioration, aquatic ecosystem sedimentation, and airborne dust pollution are some of the major ecological issues produced by soil erosion. We can lessen the effects of soil erosion by increasing the vegetation cover of the area.
